LAMP.

To all whom "it may concern:

Be it known that I, RUDOLPH E. BRUOK;

NER, a citizen of the United States, residing at Mount Vernon, Westchester county, New York, have invented certain new and useful Improvements in Lamps, of which the following is a full, clear, and exact description.

My invention relates to improvements in lamps, particularly useful for car lighting wherein extreme currents of air have to be guarded against.

It is also of particular utility in connection with lighting by acetylene gas.

In the drawings, Figure 1 is a vertical sectional view of a car lamp "constructed to embody my invention, said view being taken on the lane of the line XX Fig. 3. Fig. 2 is anot 1er sectional view taken on the plane of the line YY Fig. 3. Fig. 3 is a horizontal view taken 011 the plane of the line ZZ Fig. 1. Fig. 4 is a detail view.

1 is the frame or body of the lamp mounted or suspended in any suitable way, as by means of arms 2-2 The arm 2 may constitute the gas pipe. This gas pipe has a gooseneck continuation 3, carrying at its lower end the burner 4.

5 is a deflector supported at the base of the burner 4.

6 is a globe having a central opening or perforation. 7 at its lower end directly below the deflector 5. .The diameter of the opening 7 corresponds substantially to the diameter of the deflector 5.

8 is a central tubular outlet flue.

9 is a deflector at the top.

The flue 8 projects down to a point below the upper edge of the globe 6. The globe 6 is removably held in place by means of clips 101010 carried by a spring preferably formed of a plurality of leaves 11 of successively increasing length.

1212 are operating rods which project from the ends of the longest spring leaf and extend through suitable slots in the side of the frame 1 whereby the outer ends may be engaged by the hand to contract the spring and free the globe. The globe 6 may be provided with the usual lining at its upper edge to protect the same and to prevent rattling. 13 is a closure in the upper part of the frame 1 to prevent direct downward currents of air entering the flame chamber. This closure may act as a support for flue 8.

As is best seen in Figs. 1 and 3, the spring Specification of Letters Patent. Application filed February 4, 1908.

Patented May 26, 1908.

Serial No. 414,182.

11 is carried by a ring 14, which latter is secured to the frame 1 (but spaced apart therefrom) by bosses 15, the space between the ring 14 and frame admitting air to the flame chamber.

16 is a deflector at the lower edge of the body 1.

As will now be seen, air may enter between the globe and the deflector 16, and may proceed upwardly, as shown in Fig. 2, thence over the edge of the ring 14 and thence downwardly sweeping the inner wall of the bowl 6. Air may also enter the lower opening 7. From here this air will be deflected outwardly, meeting the down-coming currents of air which curve inwardly at or near the flame, as conventionally shown by arrow in Fig. 2. From thence the merged currents proceed upwardly through the outlet or flue 8. In the zone of the flame there will always be a substantial equilibrium so that, although a sufficient quantity of Oxygen will always be supplied to the flame, there will be no flickering or unsteadiness of the flame itself.

In this case, as in my former patent No. 854,027 of May 21, 1907, an air envelop is formed around the flue 8, which tends to prevent the deposit of any products of comustion thereon, thereby always maintaining the same bright and eflicient. This flue 8 may be made of any suitable material.

One of the advantages in this form of construction will be found in that the lamp may be lighted without the necessity of removing the bowl, or opening the lamp, it requiring merely the introduction of a match through the air admission passage 7.

In the preferable construction, both ends of the spring 11 are free and the finger pieces pass throughslots in both the ring 14 and frame 1, with the result that these finger pieces not only serve as means for manipulating the spring to release the globe, but also as supports for the free ends of the spring, they in turn being supported upon the lower edge of the slot or slots through which they pass.

By this arrangement and construction there is no opportunity for the formation of a gas pocket or an accumulation of gas, whereby an explosion may result, a feature which is of very great importance. If, during the interval between the turning on of the gas and the lighting of the same, an accumulation of gas occurred within the 1 in the upper part thereof, a bowl supported bowl or lamp, an explosion would surely result with the destruction of the'lamp, and. possible injury to' those near by. This would be particularly true in that type of a lamp in which the bowl remains in place atv by said frame at the lower side thereof, an annular ring or. deflector above the;upper edge of the bowl and projecting into the annular frame but spaced aparttherefrom,

an outlet. flue suspended from the closure at the top of the bowl and projecting into the globe and spaced apart from said ring, and a burner suspended in said bowl below said outlet.

2. In a lamp, an annular frame, a closure in the upper part thereof, a bowl supported by. said frame at the lower side thereof, an

. annular ring or deflector above the upper edge of the bowl and projecting into the annular frame but spaced apart therefrom, an outlet flue suspended from the closure at the top of the bowl and projecting into the globe and spaced apart from said ring, a burner suspended in said bowl below said outlet, a central opening inthe lower part of said bowl, and a deflector arranged between said opening and said burner.

3. In a lamp, an annular frame, a closure in the upper part thereof, a bowl supported by said frame at the lower side thereof, an annular ring or deflector above the .upper edge of the bowl and projecting into the annular frame but spaced apart therefrom, an outlet flue suspended from the closureat the top of the bowl and projecting into the globe and spaced apart from. said ring, a burner suspended in said bowl below said outlet, a central opening in the lower part ofsaid bowl, and a deflector arranged between said opening and said burner said opening and deflector being of substantially the same diameter.

4. In a lamp, a frame, a bowlsuspended therefrom, a burner suspended in said bowl, an opening in the lower .part of said bowl underneath said burner, and a deflector car ried by the burner above said opening and between said opening and said burner.

5. In a lamp, a frame, a bowl suspended therefrom, a burner suspended in said bowl. an opening in the lower part of said bowl underneath said burner, and a deflector carried by the burner above said opening and between said opening and said burner, said deflector corresponding substantially in diameter to the opening in the base of the bowl.

6. In a lamp of the character described, a frame, a central outlet flue, a closure around said outlet, a ring carried by said frame below' said closure, an air admission passage over said ring, an air admission passage between said ring and frame and between said ring and outlet flue, a bowl suspended from said frame, a burner suspended within the bowl, an air admission opening in the lower part of said bowl, and a deflector carried by the burner and between the same and said last mentioned opening.

7. In a lamp, a hollow frame, a closure in the upper part thereof, a bowl supported by said frame at the lower sidethereof, a deflector abovethe upper edge of the bowl and of the sameshape as the upper end of said bowl, and projecting into the hollow frame but spaced apart therefrom, an outlet flue suspended from the closure at the top of the bowl and projecting into and spaced apart from said ring, and a burner suspended in said bowl belowv said outlet.

8. In a lamp, a hollow frame, a closure in the upper part thereof, a bowl supported by said frame at the lower side thereof, a deflector above the upper edge of the bowl and of the same shape as the upper edge of said bowl, andprojecting into the hollow frame but spaced apart therefrom, an outlet flue suspended from the closure at the top of the bowl and projecting into the bowl and .spaced apart from said ring, a burner suspended in said bowl below said outlet, a central opening in the lower part ofsaid bowl, and a deflector arranged between said opening and said burner.

9. In a lamp, a hollow frame, a closure in the upper partthereof, a bowl supported by said frame at the lower side thereof, a deflector above the upper edge of the bowl and of the same outline as the upper edge of said bowl, and projecting into the hollow frame but spaced apart therefrom, an outlet flue suspended from the closure at the top of the bowl and projecting into the bowl and spaced apart from said ring, a burner suspended in said bowl below said outlet, an opening in the lower part of said bowl, and a deflector arranged between said opening and said burner, said opening and deflector being of substantially the same diameter.
